To all whom it may concern:

Be it known that I, LOUIS SMITH, a citizen of the United States, and aresident of Chicago, in the county of Cook andState of Illinois, haveinvented certain new and useful Improvements in Proof and TransferPresses; and I do hereby declare that the following is a full, clear,and exact description thereof, reference bein had to the ac companyingdrawings, an to the characters of re erenc'e marked thereon, which forma part of this specification.

This lnvention relates to novel proof and transfer presses for takingproofs from forms suitably locked on a bed for proving and registeringthe form and therea r, without removing the forms from the bed after thesame is in register, transferring the impressions from the forms directon printing lates for lithographic or ofiset presses. he press isdesigned for making either positive or no ative transfer printing platesor elements or lithograph or offset presses from zinc, aluminum, stone,rules, type, or cuts in one operation, in one or more colors. One ormore forms can be made on a printing plate by direct transfer fromrules, type, or cuts, to zinc plate, aluminum, or stone.

The purpose of the invention is to rovide a novel construction, whereina proo f transfer roller may be so associated with a bed on which theforms are locked and a bed on which the transfer plates, stones, orother elements, are supported that the forms may be first proved u andregistered by running the proof ro ler thereover, and thereafter theimpressions from the forms directly transferred therefrom by a transferroller or rollers to a printingelement such as zinc printing plates,lithograph work or ofiset work, thus providing in one simple press meansfor successivelyl proving and transferrin the'work, whic may be employedfor lit ograph work only or for ofi'set work only, and which may; beused also as a proving press for composing room. I

Another object of the invention is to provide a novel press of thischaracter wherein the bed that supports the printing forms may beadjusted with respect to the proof roller and to the transfer roller orrollers, so as to adjust the press to forms of different sizes locked onthe bed. Such adjustment of the bed may be efiected either in adirection and a.

, provide aluminum or stone for arallel to the axes of the proof ortranser rollers or in a direction transverse thereon, as the adjustmentmay be in both directions.

Another object of the invention is to provide novel means for s0adjusting the bed.

A further object of the invention is to provide means for operating therollers, constructed and cooperating with means for elevating therollers above the forms and printing elements so that said rollers maybe moved longitudinally of the bed without contact with certain of theforms or plates at times when no contact is desired, and in contacttherewith'when such contact is desired.

Another object of the invention is to provide a novel arrangement ofsectional tracks for supporting the rollers, in connection with meansfor giving movement to the rollers bodily of the bed and printingelements, so constructed and arranged ,as to elevate the sectionaltracks to lift the rollers above the forms and printin elements atcertain parts of the travel of t e rollers.

Another object of the invention is to rovide a novel arrangement oftransfer ro lers whereby the impression from the printing forms may beeither transmitted directly to a printing plate, stone, or the like, asa negative impression or directly transmitted to a second roller fordirect positive transfor an offset press.

the invention is to a support in a device of this character for suchprinting plates so arran ed as to permit the plates to be shifted so tat the required number of transfers ma be made on the transfer rollerand trans erred to the printing plates.

Other objects of the invention are to imfer to a printin plate A furtherobect of prove and simplify proof and transfer presses, and theinvention consists in" the combination and arrangement of the partsshown in the drawings and described in the,

specification, and'is pointed out in the appended-claims.

In the drawings Figure 1 is a fan view of a proof and transfer press emodying my invention.

Fig. 9 is a cross section on the line 9-9 of Fi 2. .i 10 is a crosssection on the line 10-1O of Fig. 3. V

The frame of the machine may be made of any suitable or convenient shapeto properl support the elements of the machine and their bearings and isshown as comprising a horizontal platform supported on legs orstandards. It has an extension 16 for a purpose to be hereinafterdescribed. $upported on said frame is a movable or ad uStable printingform supporting bed 17 and a fixed bed 65 to support printing elements66.

The movable or adjustable bed, as herein shown, is made of a widthsubstantially equal to the width of the frame and of a length to extendthroughout the principal distance between the roof roller and the fixedbed 65. .The printing plate supportin bed 65 is raised above the level othe bed 17 so that the latter in its lon 'tudina] adjustment may passpartly beneat the bed 65, as indicated in dotted lines in Fig. 1, andfor a purpose hereinafter described. The frame 15 is also provided atone end with a transverse extension 76 to en port an adjustable bed 78for printing ates 7 7 herelnafter described. The be 17 may be termed adouble bed inthat it is arranged to support two or more formswhich areadapted to be registered to produce the ultimate composition.

For convenience and certainty, the forms supported on the bed 17, areherein termed prmtin forms; the plates 66 supported on the fixe bed 65are termed negative rinting elements, and the plates 77 supported on thead'ustable bed 78 are termed positive printing elements. These terms arenot however, intended as limitin terms but are descriptive of thepresent 1 lustration of the invention.

Said bed 17 supports frame or chases 18 in which are locked inany,suitable manner the forms 18' best shown in Fig. 1. The particularforms shown in Fig. I may be the down and cross line forms tat arecomposed in proper register for'printing cross ruled sheets inaccordance with the method disclosed in my prior United States LettersPatent Number 1,210,862, granted January 2, 1917. The cross ruled formsmade in acmay be associate cordance with the aforesaid method, may bearin addition to the down and cross lines, such printing as may bedesired. As shown in Fig. 1, the forms 18 are of dimensions to occupyallotted rectan lar s aces 18 on the bed, and, as herein 3 own, t etransverse width of each space is equal to one-half the len h of theroof and transfer rollers. ssuming t at proofs are to be made of downand cross lines of a cross ruled form, after proofs have been taken fromthe full line forms shown in Fig. 1 on one-half of the proof roller, thebed supporting said forms may be shifted so that t e forms noon thepositions indicated in dotted lines in '*1 1 and the same proofs takenon the other half 'of the proof roller. I

If desired, however, other forms, such as Slates, rules, type, or cutsof the same or ifierent colors be locked on the bed to constitutesmaller forms, in which event it is desirable to adjust the movable bedboth laterally and longitudinally of the frame so as to bring the formsin proper registration with desired longitudinal and circumferentialareas of the proof and transfer rollers.

The means herein shown for laterally adjusting the movable bed comprises-a threaded shaft 20 which is rotatably mounted in a suitable bearing 20on the frame and is threaded throu h a nut 21 that depends from the bed'ig. 9). Said shaft is-provided with a hand wheel 22 and a graduateddial; cooperating ointer 22' (Figs. 2 and 5) with said shaft so as tofacilitate the registration of the forms relatively to the proof andtransfer roller. The extension 16 of the frame 15 is provided to supportthe bed 17 when the latter is adjusted to occupy the position indicatedby the dotted lines in Fig. 1.

25 designates'the proof roller which is located at t e forward end ofthe frame. It is supported on a. shaft 25' that is'rotatively mounted inbearings carried by bearers 40 which are in turn supported on tracks 41,41' the latterfixed relatively to the frame and the former verticallyadjustable, as hereinafter described. 26, 26 desi nate spur giars whichare fixed to said sha t 25' or to t e roller 25 and mesh with theupwardly facl tgg teeth of racks 27, 27 that are suppo on the frame 15at the sides thereof whereby, on rotation of the roof roller, the

.latter is caused to rotate on its axis and-also be carried bodilylengthwise of theadustable bed. The said proof roller is re.- tatedbnits Taxis and caused to move along the glate by means of a crank 28fixed to the sha 25'. The track sections 41 are. adepted to be raised inany suitable or preferred manner to lift the proof roller out of contactwith the forms or certain of them, as v will hereinafter more fullyappear. 29 designates a group of inking rollers of any to predeterminedperipheral areas of the proof roller comprise a rotative shaft 32 thatis disposed transversilly of thefframe and is mounted in sui 32'thereon. Said shaft 32 carries near "'1' end pinions 83 which areadapted to mesh with the downwardly facing teeth of racks 34 suitablyfixed to the bed 17. The shaft 32 is provided at one end with a handwheel 35 by whichit is rotated, and a graduated dial 35 and a'coiiperating pointer may be associated with the shaft to measure therotations of the shaft and thereby facilitate registration of the formsrelatively to the" proof and transfer rollers. I

Through the coaction of tlfe adjusting shaft 20, and nut 21, on the onehand, and the shaft 32 and the pinions 33 and racks 34, on the otherhand, it will be observed that the bed 17 may be shifted eitherlaterally or longitudinally of the frame to efiect'desired registration.of the forms relativelglto the proof and transfer rollers and to a justthe press to forms 'of different sizes The threads of the-shaft 20 andthe teethof the pinion 33 and racks 34 will be made of such pitch as togivea desired delicacy of adjustment of the bed in either directlon,Endthe dials 22 and 35 are graduated to indicate such adjustments; Itwill be understood that the ppinters'of said dialsare geii-ed in anysuite is manner to the shafts 20 and 32 to cause the pointers to sweeover the dials as said shafts are turned to just the 'bed.

The shoes vor bearers 40, in which the shaft 25' of the proofroller 1smounteflbear upon the fixed tracks 41' of the frame at the front end ofthe press when the proof roller is in its inoperative or' retractedposition and when stai roller is moved over the forms 18 said bearers 40are supported by the sectional tracks 41. When the forms are of suchsize as to occupy less area than all of the bed, or when provingmulti-color forms on'the bed, it will 0 necessary in sortie parts of thetravel of the proof roller, over the form to lift the same away from orout of contact with certain of the forms. Such lifting of the proofroller'may be effected by raising the sectional tracks 41 and saidtracks may be raised in any suitable or approved manner. for raising thetracks are made as follows: The said track sections are provided attheir ends and on their under sides with shallow cai'n faces adapted tobe engaged by the inner arms of levers 43 that are pivoted at 44 to themachine frame. When the levers 43 are in their outstanding positions,

" If the The means herein shown or normal to the sides of' the frame, asshown in Fig. 3, the arms 45 are engaged with said cams and serve toraise the tracks to positions indicated in Figs. 5 and 6. When the proofroller is located abreast said tracks and the bearers 40 are supportedon the raised tracks, said bearers and the proof roller are raised so asto lift the roller above the forms. When the levers 43 are swun atoblique angles to the positions indicate? in Figs. 1, 2, 5, and 7, thetracks 41 descend to the level of the fixed tracks 41' of the frame tobring the proof roller in contact with the forms on the bed as desired.

designates a transfer roller, the shaft 51 of which is mounted insuitable bearings carried by bearers 56 that are adapted to bear on thefixed tracks 41' of the frame or upon the sectional raisable andlowerable track sections 41. The shaft 51 of said transfer roller isadapted to be rotated on its axis through the medium of a hand crank 52attached to the said shaft. At the ends of the transfer roller are spurgears 53 which mesh with the upwardly facjn teeth of the rack 27. abovereferred to, w ereby when the crank 52 is turned, and there through thetransfer roller 50, the engagement of said gears 53 with the tracks 27causes the transfer roller 50, not only to rotate on its axis, but alsoto be moved bodily lengthwise of the beds 17 and 65. Thus the transferroller may be moved over the forms 18' after the same have been provenand said transfer roller may be thereafter moved backwardly over the bed17 and to the bed to transfer the impressions received thereby on theprinting elements 66 suported on the fixed bed. When said trans erroller 50 is being moved forwardly over the fixed bed 65, the tracksections 41 are elevated to lift said roller out of contact with theprinting element 66 and when the roller is returned to said printingelement after receiving the transfer from the forms 18', the tracksections are depressed to cause the impression received by the transferroller to be transferred to said printing element. Also the tracksections 41 may be thus raised to lift the transfer roller out ofcontact with any one of the forms 18' not to be transferred in anyparticular operation of the machine.

plates 66 on the bed 65 are to be used as lithograph plates on alithograph press, the transfer of the forms on said plate or elementwill be negative or the same as shown on the forms 18', and said plates7 after receiving the transfer from the roll 50 are removed to beprepared for the lithograph press and used as printing plates in theusual way.

At times itis desirable to move the transfer roller 50 bodily lengthwiseof the bed 5 bed without rotating it on its axis is shown in Fig. 4. Astherein shown, the shaft 51 of the transfer roller is grooved to receivekeys 60, 60 having hand pieces 61 exposed at the ends of the shaft,whereby the keys in may be shifted in the keyway. The heads of thetransfer roller 50 are provided with keyways 63 and the spur gears 53are also provided with keyways 62. When the broad inner ends of the keys60 are engaged partially in the keyways 62 of the spur gear andpartially in the keyways 63 of the transfer roller, said transfer rolleris locked to the gears 53 so that when the shaft 51 is rotated, throughapplication of power to the crank shaft 42, the transfer roller will becaused to rotate on its axis and also to be moved bodily longitudinallyover the bed through the coaction of the spur gears 53 and the racks 27.When the keys 60, 60 are shifted so that its broader inner ends liewholly within the keyways 63 of the spur gears 53, said gears may rotatewith the shaft 51, without, however, transmitting rotation to thetransfer roller 50. In the latter so adjustment of the parts thetransfer roller may be shifted bodily, through the coaction of the gears53 and rack 27 with respect to the bed without turning on its axis. Thekeys may be connected in any suitable manner for mutual operation, asfor instance in the manner shown in Flg. 4. a,

When it' be desired to transfer the impressions'from the transfer roller50 for positive impression to printing elements for 40 ofi'set presswork, the impression from the transfer roller 50 is transferred directlyto a second transfer roller 70 that is so mounted on the frame that saidtransfer rollers 50 and 70 may be geared together to rotate inperipheral contact with each other and at equal speed and therebytransfer the impression. from one roller to the other.

The said transfer roller 70 is mounted on a shaft 71 which is rotativelsupported on and is carried by bearers 71 that are supported directlyon'the fixed tracks 41' of the frame. In order to cause the transferrollers 50 and 70 to be rotated in contact with each other and,at equalperipheral speeds, said rollers are provided at their ends with meshinggears 72, as best shown .in Fig. 3. The shaft 71 of the transfer roller70 is provided with a crank 73 by which the latter roller is turned onits axis and, through coaction of spur gears 74, '74:

at the ends thereof with the racks 27 before described, said transferroller may be caused to be moved bodily over and in contact with theprinting element 77 to trans- 66 fer the impression received from theroller length 0 50to the positive printing elements for off set work.

When the transfer rollers 50, 70 are to be rotated in peripheral contactwith each other to transfer. an impression from one to the other, broad,iiiner ends of the ke s 60, 60 of the transfer roller 50 may e forcedinwardly wholly into the keyways 63 of the transfer roller 50, wherebysaid roller is released from the spur gear 53 so that the roller may berotated on its axis without, however, causing said roller to move bodilyrelatively to the frame. The transfer roller 70 may be likewise providedwith control- 'ling keys 7 5 by which said latter roller may marytransfer roller 50 to the secon ary transfer roller 70, and theimpression thereafter transferred from the latter roller to the printingelement 77. i

The bed 78 is adjustable transversely of the frame 15 so thatimpressions may be transferredtoa number of printing elemlents 1717whose a ate length is reater t an t e fiis ransfer roller Suchadjustment of the bed 78 may be effected by providin the bed withdownwardly facing racks 80 igs. 3 and 7) which are adapted to be engagedby pinions 81 that are fixed to a rotative shaft 82 disposedtransversely of the frame 7 6 and mounted in suitable bearings therein,and provided at one end with a hand cran In the operation of themachine, the proof roller will turnon its axis during the time it isbeing moved bodil rearwardly over the forms to receive roo impressionsthere from, and will be re eased from its gears so as to be carriedbodily forwardly over the forms without turningon its axis, said proofroller returning to its normal or inoperative position while theinterrupted or cutaway portion thereof faces downwardly. It will also beunderstood that the transfer roller 50 will be rotated on its axis whentraveling forwardly over the printing forms 18 to receive theimpressions therefrom, and that when traveling backwa-rdly over themovable and fixed beds 17 and 65, respectively, it will be released fromits gears so as not to turn on its axis, and during its return movementthe cut away or interrupted ortion thereof will face downwardly. So liewise, the secondary transfer roller 70 will turn on its axis when movinrearwardly over the printing element 77 ut will be disengaged from itsgears and return forwardly to its inoperative position without rotatingon its axis. a

shown for releasing the gears from the proof and transferrollers aremerely illustrative as one form of such means, but it will be understoodthat any preferred or known form for. controlling the movement of therollers to cause them to rotate when traveling in certain directions andto hold them from rotation when traveling in other directions may Inevent that the key means herein shown be employed, the frame may beprovide with any suitable cams to cooperate with the keys, or in placeof the keys known forms of ratchet release and co-acting projections onthe frame may be employed.

So far as the structural details of the various mechanisms by which tooperate the proof and transfer rollers and by which to elevate anddepress the rollers at the desired times and 'by which to adjust themovable beds 17 and 78 are concerned, such details may be considerablyvaried from those shown, said details bein merely illustrative ratherthan limiting. t is believed, however, that the combination of the proofand transfer rollers operating on a single frame in connection with amovable or adjustable printing form bed and with a bed or beds forsupporting the printing elements to receive the impressions from thetransfer rollers is novel and such combination and the generaladaptation of the means to effectuate said combination are hereinbroadly claimed.
